Application m February 4, 1919. I Serial no. 275,048.

To all whom it may concern Be it known that I, MAX Pon'rzson, a c1t1-"zen of the United States, and a. resident of Clifton, in the county ofPassaic' and State of New Jersey, have invented a new and ImprovedBurling or Examining Machine, of which the following is a full, clear,and exact description.

This invention relates 'to examining or burling machines and has for anob ect the provision of an improved construction wherein the cloth ispassed over a table in such a manner that the person doing the examiningmay properly observe all parts of the cloth without straining the eyes.

Another object of the invention is to provide a machine for examiningwhich will move a piece of cloth across an examining table quickly foracertain length of time by numera 1 indicates 'an u per frame and thenvery slowly for a certain length of time, or stops for a short tlme.

A further object of the invention is to provide a machine for examiningwhlch may be adjusted to cause the cloth to pass horizontally across anexamining table and cause it to pass vertically between guiding rollersfor examination from one side.

In the accompanying drawings:

Figure 1 is a side vlew of a machine disclosi'ng an embodiment of theinvention, certain parts being broken away and others shown in dot forillustrating the construction more exactly.

' Fig. 2 is a top plan view of the machine shown ,in Fig. 1.

Referrin to the accompanyin drawings supported by any desired num er ofuprights 2 as well as a framework 3whioh' carries a table 4. The table 4.is provided with rollers 5 and 6 over which a cloth 7' (known in thetrade as a piece) passes as" it moves across the table 4. Beneath thetable 4 is arranged a motor 8' of any desired kind, as 'for instance anelectric motor, with which is connected a pulley 9" over which a belt 10passes. Said belt passes over a second pulley 11 on shaft 12 and theshaft 12 carries pulleys-13 and 14 for driving the belts 15 and 16, belt16 passing over pulley 17 connected to the roller 18 used in pulling thecloth 7 through the machine. These members and also others are driven bymotor 8, which is provided with a switch of any desired kind adapted tobe opened and closed bythe rod 18 connected to lever 19.

Specification of letters Patent.

Patented Aug. 12, 191.9.

The lever 19 is pivotally mounted at 20 so that when the treadle: 21 ismoved downwardly rod 18 will be moved downwardly and the switch will beopened. A reverse movement of the treadle under the action of chain 22will close the switch. This chain is connected to a pivotally mounteddrum 23 whereby the chain onarm may be readily grasped by the operatorstanding on the platform 24. In case the platform 25 is the lever 27 sothat when the treadle 28 is depressed the rod will be moved.

Arranged at any convenient point, preferably near the table 4, is abracket 29 con- 'nected to the upper frame 1, said bracket carryingrollers 30 and 31, and a driving roller 32, whereby the cloth 7 as itleaves' the wagon 33 is pulled u wardly and moved properly through thero lers-on bracket 29. As the cloth leaves roller 30 it passesdownwardly over an idler 34 and from thence used bar 18" is pivotallymounted at 26 on] over idler 35 to the roller 5 and then across thetable .4. As it leaves the table 4 it passes over roller 6, idler '36,idler 37, idler 38 and the speed var ing roller 39 to the' idler 40.From the id er 40 the cloth passes around the driving .pulley 18 andfrom thence over the idler 41 to the discharge roller 42. As it leavesthe discharge roller 42 it passes through a swinging folding device 43ofan old and well known type, which is swung back and forth in order tofold the cloth in the Wagon 33. The means for swinging member 43 mayconsist of an arm 44 rigidly secured to member 43, or connected to thegear wheel 45 by a link 46, said gear meshing with pinion 47 secured tothe rod or shaft 48 carryin the roller 42. The

shaft, 48 carries a pul ey 49 which accommodates the belt 50 which beltpasses over a pulley 51 secured to theshaft of roller 18, which shaftalso carries pulleys 17 and 52, pulley 17 accommodating the belt 16,

while pulley 52 accommodates the belt 53.

This last named belt passes over pulley 54 secured to the'shaft of thespeed varying roller 39. In this way power is transmitted to the variousrollers and the folding device 43. V

In order to properly actuate the speed varying roller 39 said roller isconnected to crank arms 55 journaled at 56 on the upper frame 1, butrigidly secured to crank arms 57 which are connected to the rotatingdisks 58 by links 59. The disks 58 as shown in 3 5 cers.

Fig. 2 are rigidly secured to shaft 60 on which pulle 61 is looselymounted, but prevented longitudinal movement. Pulley 61 is provided witha clutch face 62 actuated with 5 the clutch member 63 which is splinedoil the shaft (30 and operated from any suitable lever so as to be movedinto and out of engagement with the clutch face 62, so as to throw theclutch into and out of operation and thereby cause the actuation of theroller 39 or stop its actuation. From the construction described it willbe seen that when the power is turned on the roller will move upwardlyand downwardly in the regular cycle of movement and consequently willpull on the cloth 7 when moved in one direction and will release thecloth when moved in the opposite direction, notwithstanding theconsta'nt pull-created by roller 18. This motion of roller 39 will causethe cloth to pass over the table 4 at one period of time comparativelyrapidly and at another time comparatively slowly. If desired the partscould be arranged so that the cloth would completely stop its movementacross the table, though ordinarily if it will slow down and then speedup the desired results are secured.

An examining table of this kind is used in factories and elsewhere forexamining cloth after it has been woven so as to detectobjectionablespots, knots, or the like. In case the cloth is found to have knotstherein or lumps the xamining person will remove said knots by the useof a special pair of pin- This is done while the cloth is moving veryslowly across the table, but as the person examinin the cloth mustconstantly look at the tab e the change in speed relieves the eyesalmost to the same extent as if the cloth stopped, while at the sametime allow-' mg the general feeding of the cloth through the machine tobe at a satisfactory speed and also allowing the proper examination andremoval of knots and other objectionable matter found in the cloth.

In some instances it is desired to look through the cloth instead ofexamining the same on a table similar to table 4, when this is the casethe cloth, or piece, is not passed over table 4, but is caused to movefrom roller 38 over rollers 64:, 65, 66 and 67 to roller 55. This willcause the cloth to travel in a vertical line adjacent platform 25 sothat a person examinin look through the cloth. I desired either anatural-or artificial light may be arranged adjacent the verticalsection of the piece in order that any faults may be more readilyobserved.

What I claim is:

1. An xamining machine of the class described, comprising a plurality ofrollers,

one of which constitutes a cloth-feeding roller, a swinging membermovable across the path of the cloth, andpositive operating mechanismcausing said member to move in both directions to vary thespeed of themoving cloth.

2. An examining machine of the class described, comprising aplurality ofrollers, one of which constitutes a cloth-feeding roller, a pair oflevers, a member carried by -the levers, and positive actuating meansthe cloth may causing an oscillation of said levers to move varying theuniform travel of the cloth.

through the machine, said means comprising a roller, a pair of pivotallymounted supporting arms connected with the roller, means including arotating disk for rocking said roller back and forth and causing theroller to move back and forth transversely of the length of the cloth sothat the cloth at one time will have a longer path of travel than atanother, and means connecting said disk and said driving means so thattheywill operate in timed relationship with each other.
